Definitions

  • the present invention refers to a corner joint for profile sections provided with one or more longitudinal channels, in connection with the outside of the profile section via a likewise longitudinal slot opening and which channel constitutes a n attachment for a nut means which cooperates via screw means with connector fittings, wherein each screw means is provided with a lock means which is located in the slot opening between the nut means and the connector fittings, which lock means is provided with a screw opening and means for locking the nut means against rotation out of a locking position.
  • Profile section beams may for example produced by extruding aluminum, with one or more longitudinal channels, in connection with the outside via a likewise longitudinal slot opening. These channels may be used for joining two or more sections by means of screw joints and connector fittings, e.g. for building a stand frame.
  • One purpose of the present invention is therefore to provide a screw joint, by which the nut means can not unintentionally be displaced from its position of locking.
  • the lock means is provided with at least one boss which during rotation of the nut means from its locking position cooperates with a shoulder on said nut means, in order to position the nut means and facilitate its removal from the channel.
  • FIG. 1 shows a lock means which is a part of the screw joint according to the invention
  • FIG. 2 shows a screw joint according to the invention during assembly at a profile section
  • FIG. 3 shows the same screw joint as in FIG. 2 in its position of locking
  • FIG. 4 shows a screw joint intended for a L-coupling in an exploded view
  • FIG. 5 shows a screw coupling intended for T-coupling in the assembled condition.
  • the lock means 10 shown in detail in FIG. 1, is long and narrow, rectangular with a width substantially corresponding to the width of the nut means 11 (see FIG. 2 - 5 ). In the assembled position, the lock means 10 will be located inside the slot 12 on a profile section beam 13 , wherein a screw 14 extends through the opening 15 into the longitudinal channel 16 of the profile section 13 cooperating with a screw threaded hole in the nut means 11 .
  • a countersink section 20 A of lock means 10 has the same width as the nut means 11 and has been made at an acute angle to the longitudinal direction of the lock means. “Adjacent to the angles, of countersink section 20 a are end sections 20 b , which, with countersink section 20 a have rectangle formation, defined by the side flanges 19 and ”the longitudinal sides 18 , just opposite the screw opening 15 .
  • the nut means 11 When tightening the screw 14 , the nut means 11 will “bottom inside the countersink section 20 a , and form a continuous planar surface with the end sections 20 b , and contact ”the edges 21 of the countersink section for support. This means that the nut means during tightening will be locked in a stable position of locking, in which the two shoulders 22 of the nut means 11 act as locking for the entire screw joint inside the channel 16 .
  • the nut means 11 may move out of the countersink section 20 a after which it may turn out of its locking position. Now an obliquely cut edge of the shoulders 22 of the nut means abuts a corresponding oblique boss 23 at each end of the lock means 10 , said two bosses positioning the nut means 11 , so that the screw joint may easily be removed from the section 13 .
  • the lock means 10 may preferably be manufactured from a plastic.
  • FIG. 4 shows one embodiment where L-shaped connector fittings 24 from plastic are moulded in one piece with the lock means 10 .
  • the lock means may, as is shown in FIG. 1, be manufactured as separate units.
  • FIG. 5 shows another embodiment with T-shaped connector fittings 24 .
  • the invention is not limited to the above described embodiment, instead more variants are conceivable.
  • the connector fittings may be designed differently.
  • the lock means and the nut means may also be differently designed from what is shown.
